WILLIAM A. ZEIDLER AND PAUL M. ZEIDLER, OF NEW YORK, N. Y., ASSIGNORS T0 SOLACE COMFORT SERVICE CORPORATION, A CORPORATION OF YORK.

VENDING-MACHINE.

T 0 all whom it may concern:

Be it known that we, WILLIAM A. ZEIDLER and PAUL M. ZEIDLER, citizens of the United States, residing at New York, in the county of New York and the State of New York, have-invented a new and useful Improvement in Vending-Machines, of which the following is a specification.

This invention relates to improvement in automatic coin or check controlled vending machines, and it consists of the features of construction and combination of parts hereinafter described and claimed.

The objects of the invention are to correct the defects frequently met with in this class of apparatus, namely: arching or clogging of the articles to be dispensed, interrupting the feed to the ejector, possibilities of illic- -itly operating the machine and the occasional liability of non-delivery of the article purchased.

Its essential feature of novelty resides in our improved means of insuring feed to the ejector at each operation by agitating the stack in four different directions. Also in our improved means of locking and unlocking the operating mechanism so as to insure proper delivery. These and other features with their functions and operations, are clearly set forth in the accompanying description and drawings, in which Figure 1 represents a view of the machine with the front removed, showing the ejector and the agitating mechanism, and the method of locking the coin box in lace.

Fig. 2 represents a front elevation of the lower part of the machine, showing the operating handle and the delivery aperture.

Fig. 3 represents an enlarged front view of the ejector with its actuating gears.

Fig. 4 represents an enlarged view of the locking mechanism removed, with the coin slot shown in section.

Fig. 4? represents an enlarged side elevation of the coin box and its locking mechanism.

Fig. 5 represents an enlarged back view of part of the locking mechanism shown in Fig. 4, with a coin in position, indicated by dotted lines. 4

Fig. 6 represents an enlarged plan view of the ejector with its operating and locking mechanism, and also represents a sim lar view of the coin box and its locking mechanism.

or swinging member 3, hinged to the inner 1 side of top of the casing 1 through rollers, '3, located in depressions, 3"3 in either side of the member 3, causing it to swing in an arc. A coiled spring, 3, located between the inner side of the side wall of the casing and the member 3, serve to keep the rollers 3' in contact with the cams of the ejector 2 at all times.

Another oscillating member 4 Whose normal position is horizontally disposed, is,

hinged at its inner end to a block, 5, having a curved face 5 in order to clear the ejector 2; and the lower end of the face of the block '5 is also curved as shown, conformingto the 'face of the block 6 in order to provide a guide-way from the pocket 2 of the ejector 2 to the delivery chamber 7. Both the blocks 5 and 6 are screwed or otherwise securely fastened to the bottom of the casing 1 as shown. I

It has been shown that the cams, 2 2 2 2 act on the rollers, 3*3, of the swinging member 3, causing it to oscillate. At the lower end of the member 3, an eye 3 is provided, into which one end of a rod 8 is pivoted. The lower end of the rod 8 is pivoted to one arm of a bell-crank 9, the other arm of which is in turn pivoted to a rodlO which is pivoted in an eye 4? of the member 4:. Thus, when the member 3 is swung back and forth in an are by the cams 22, motion is transmitted through therod 8, the bell crank 9, and therod 10 to the member 4, causing it to move upward and downward,

and causing the packages 11 indicatedby the dotted circles, to roll toward the pockets, 2'" of the ejector 2. The members is cut away at the hinged end forming a portion which extends between the sides of the cams of the ejector 2 as shown. It will be seen that the inner face of the member 3 is provided with urge the impinging package, 11" upward and inward. as'it moves forward. This action, together with. the inward and outward movement of the articles or packages by the member 3, and the upward and downward, as well as inward and outward movement of the articles or. packages by the member 4,

effectually prevents arching or packing, and insures positive feed to the pockets 2--2 of the ejector 2.

In order to rotate the ejector 2, a handle 12 is mounted on a short spindle 13 which passes through the front of the casing; the other'end of the spindle 13 being provided with a small pinion 14 which meshes with a gear 15, screwed or otherwise securely fastened to the front end of'the ejector 2. It is desiredthat theejector makebut onehalf revolution in order to discharge a single article or package. To this end a rotating toothed member 16, having two pockets, Mi 16 in its face, one on each side, diametrically opposed, into which a awl, 17, actuated by a flat spring 18, rests. he inner side of the member 16 is provided with- 'curved projections, 16 16", which are held in touch with a back plate 19, by a coil spring 20, set in a pocket 1 inrthe front -of the casing 1, so that the'member 16 is always in yielding contact with the back plate 19. The member 16is' provided with a centrally disposed square hole, 16", through which it is mounted on the squared end of a spindle, 21; the spindle 21 being mounted on and pinned to the gear '15, fastened on the end of the ejector 2, and

. journaled at itsother end into a bracket 22,

' as shown.

While the pawl, 17, rests in the pocket, 16,'the ejector 2 is locked and may only be turned the length of the pocket 16. In order to unlock themechanism and permittheejector' 2 to'be'rotated, a coin 2 is dropped into the coin slot, 24 of the member 24, and falls into the position shown in Figs. 4. and'5, resting between one end of a curved ro'ection 16 and a 111 16 of the member 16. As-the pocket 16* is moved "toward the pawl 17, the coin 23 acting as a roller, lifts the pawl from the pocket 16*,-

permitting the ejector 2 tobe rotated onehalfrcvolution until the pawl 17 drops into the opposite pocket, locking the mechanism. The coin meanwhile has traveled forward until it drops into the chute 25, and thence 'to' the coin b02126.

' The coin box 26 is inserted into the bottom. f of'the casing 1 as shown, and is locked into position by; means of two members 271-27, one on' either side, and hinged to the inside of the bottom of the casing 1. A coiled spring, 28 connects the two hinged members 2727, which are provided with'arms,

27*27, extending forward, embracing a turned by its key, not shown, and the cam the remaining floor and a side of said chain here 2727 holdin it firml in aosition and preventing its removal. IVhen it is desired to remove the coin box the lock 30 is 29 forces the arms 27 -27""-, apart against 7 the spring 28, disengaging the rim 26 and releasing the box,

A counter 31 is provided, having an actuating'arm 31, which is operated by pins, 2'2 on the ejector 2, keeping an accurate account of the operations of themachine.

In operation, a coin is dropped into the coin slot 24" and the handle 12 turned slightly to the left in order that the coin may fall into its operating position, then moved to the right until the coin, acting as a roller, raises the pawl 17 permitting'the ejector 2 to rotate one-half turn, when one articleor package is released to fallinto the delivery chamber 7 c While the device as illustrated and described is designed to handle cylindrical objects, we do not wish to be restricted to this form alone, as a variety of merchandise may be handled and the form of the machine may be changedv without departing from the spirit of the invention,

We claim: f v
